TPS53689TRSBR TI Power Management IC | 40-WQFN (5x5) | Dual Output, PMBus

Product Overview

The TPS53689TRSBR from Texas Instruments is a highly integrated, dual-output, step-down controller with PMBus interface, designed for high-current, low-voltage applications. It features advanced control topologies for fast transient response and high efficiency, making it ideal for powering core rails in servers, telecom, and data center equipment. The device operates from a 4.5V to 17V input supply and provides two independent output voltages as low as 0.25V with ±0.5% accuracy. Housed in a compact 40-pin WQFN (5x5 mm) package, it supports up to 1MHz switching frequency and includes comprehensive protection features.
